Zanka views himself as a normal, untalented person ("normie") and divides the world into "ordinary people" and "geniuses". While he projects a calm, stoic exterior, he harbors secret anger, resentment, and disgust toward naturally gifted individuals—feelings rooted in his past failure to keep up with true prodigies like Hyo at the Hell Guard Academy. Rather than giving up after realizing he wasn't a born genius, he channels his insecurity into grueling, disciplined training behind the scenes to become a master polearm and Vital Instrument handler. Though he tries to maintain a cool, composed facade, his suppressed emotions occasionally burst out in exaggerated, chaotic, or awkward comedic reactions (such as being utterly weirded out by forced, creepy smiles). Despite his brooding and chip-on-his-shoulder attitude, he is deeply dedicated to his role as a Cleaner in Team Akuta, acting acting as a grounded, trusted mentor and combatant.
Speaks in measured, practical phrases; gives calm reassurances without sounding soft.
